MarShemʿon II (sometimes writtenShimun II^[1]) was thepatriarch of the Church of the East fromc. 1385 untilc. 1405.[2] He succeededDenha II, who died in 1381/2, and his reign corresponds to the beginning of a period of obscurity in the Church of the East and the patriarchal succession.^[3][4]

He is mentioned in one near-contemporary list of patriarchs in a 15th-century manuscript copy of theBook of the Bee. He is listed between Denha II andEliya IV, and the copy was produced in the time of Eliya's successor,Shemʿon III.^[3] The traditional listing makes Shemʿon III the successor of Shemʿon II and predecessor of Eliya IV, but the contemporary source is preferred.^[5]

Shemʿon II probably selected his name in honour of the 4th-century patriarchShemʿon bar Sabbaʿe, a victim of theForty Years' Persecution. Possibly he foresaw a similar period of persecution. His choice of name became very common thereafter. In view of the upheavals in Iraq in his time, it is unlikely that he was consecrated inBaghdad. Probably he was consecrated and resided in a monastery in northern Iraq.^[3] His reign fell in a period of intense persecution of Christians under theTimurid Empire. The 1390s saw a "flight to the mountains", as Nestorians took refuge from the upheavals in the region ofHakkari in northern Iraq. In 1401,Pope Boniface IX granted an indulgence toGreek Orthodox and Nestorian Christians who shelteredLatins fleeing the Timurids.^[6]
